Modbus POE ETH Relay - module with 8 relays and Ethernet communication

Description

Industrial module with an Ethernet interface that allows you to control 8 relays via the RJ45 port. It uses Modbus TCP protocol, supports PoE (Power over Ethernet) and is equipped with a rail-mounted housing. The module is extremely easy to use. With fast communication, stability, reliability and security, it is an ideal choice for industrial control applications and/or applications requiring high communication standards.

The device has a flash-on, flash-off function, thanks to which you can briefly turn on the relay and then turn it off automatically by passing the appropriate argument to the command. It supports a wide power supply range from 7 to 36V and PoE power supply. Additionally, it offers support for controlling relays via the MQTT protocol and allows for flexible management. The module comes with the Alibaba Cloud MQTT demo application.

The use of optical isolation provides protection against interference from high-voltage circuits, and the circuit ensuring immunity to improper connection protects against accidental damage to the system. High-quality relays with a maximum load of up to 10A at 250VAC/30VDC guarantee operational reliability. The module is enclosed in a rail-mounted ABS housing, which facilitates installation and ensures safe use. Additionally, 4 LEDs and network indicators provide information about the MCU status and signal transmission.
